Google maps

Since October 2006, we have presented the distribution of each species using Google Maps. Records are presented in two ways, namely as point records or as Quarter Degree Squares.

Point records

For an example of point records, click on the following link, which is a map of Tridax procumbens records.

This plots our records of the alien composite, Tridax procumbens. This species has been chosen because it occurs in all 9 countries.

If you click on one of the teardrops, it will display some details of the record.

Quarter Degree Squares

The records for the same species, plotted as Quarter Degree Squares, are at the following link.

Note that the necessary porgramming to incoprate Quarter Degree Squares from the northern hemisphere has not yet been done.
